PARAMETRICAL PHENOMENA UNDER ON-MACHINE PROCESS CONTROL
Вестник Донского государственного технического университета, 2018 The problem on the stationary tool trajectories instability relative to the workpiece taking into account the periodic parameter variation of the interacting subsystems and of the dynamic coupling formed under cutting is considered. Parameter changes are

Analytical prediction of stability limit in turning operations [PDF]
, 2006 Unstable cutting due to chatter vibrations is one of the most important problems during metal cutting operations. Chatter can be a limitation for productivity and surface quality in turning operations, especially when long and slender tools and parts are

Advanced Science, EarlyView.This study identifies CRISPLD2 as a key protector against IVDD. By regulating ferroptosis through the CRISPLD2–miR‐548I–IL17A axis, CRISPLD2 maintains NPCs homeostasis and reduces oxidative stress. Restoring CRISPLD2 expression effectively alleviates disc degeneration and highlights a promising therapeutic strategy for discogenic low back pain ...

Advanced Science, EarlyView.We have developed a glucose‐triggered on‐demand drug delivery CF‐CPGaMPN hydrogel based on borate ester bonds. It inactivates microbes, releases oxygen, and enables on‐demand drug release in high‐glucose environments to promote healing of diabetic wounds. Single‐cell sequencing reveals that the CF‐CPGaMPN hydrogel significantly alleviates dysfunctional
